BRICK-MACHINE.

Specification of Letters Patent No. 9,785, dated June 14, 1853.

To all whom t may concern:

Be it known that I, ALEXANDER I-IirPoLiTF. SaiursoN, of New Orleans, inthe parish of @rleans and State of Louisiana, have invented certain newand useful Improvements in Brick-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, making a part of thesame, in which- Figure l, represents an end elevation,

looking toward the driving gear. Fig. 2, represents a side elevation,looking toward the pressing and delivery apparatus, &c., and Fig. 3,represents a top or birds-eye view of the whole.

Similar letters iii the several figures denote the same parts.

The nature of my invention consists in combining with the mold wheel,pressing and delivering apparatus, the carrying chains or theirequivalents with suitable projections thereon which furnish from areservoir or boX and carry forward to the delivery followers, the boardsor platforms, upon which the pressed brick are received and carried toany convenient point for arranging them in the drying house or kiln-wsome portions of the apparatus having a continuous, and othersa'reciprocating or intermittent motion, but the whole being so timed asto operate with perfect uniformity with each other.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawings.

Motion is communicated to the machine. through a band `or endless beltpassing around the pulley A, on the shaft c, and another pulley H, onthe shaft G,-there being on the farther end of the shaft G', two pulleysF, F, (Figs. 2 and 3) one fast, and the other loose, for throwing thepress into and out of operation, in a manner well known tomeclianicians, and to which said fast pulley F the first moving power,whether steam or otherwise, may be applied. A loose pulley is alsoarranged alongside of the pulley A, on the shaft, for a purpose similarto that just described. On the shaft c, is also arranged the balance orfly wheel B, and a spur gear wheel or pinion E, which meshes into andoperates the large cog wheels F, F,-the one above, and the otherimmediately below it,-said cog wheels beving of equal size. The shaftsG, of the wheels F, F, each carry an intermediate spur gear of equalsize, which operate the two `wheels I-I, I-I, on the shafts I, I,-one ofwhich shafts is placed near the top, and the other near the bottom ofthe press. These wheels and pinions should be of such size as to give auniform and simultaneous movement to the shafts I, I, which operate the`other port-ions of the machine, as will be described.

On the shafts I, I, are arranged cams or eccentrics, which operate thepitmen M, can rying the followers O, O, so that two followers shallapproach each other from above and below, and meet in the mold on theclay, and thus give to the clay equal pressure from above and below atthe same time the space between the ends of the followers defining thesize or thickness of the brick to be formed. The pitmen M, may beconnected to and operated by the cams, through a strap, yoke, frame orguide so as to give a reciprocating motion to the followers, or a commontoggle, or elbow joint may be used, and produce the same effect. On theend of the upper one of the shafts I, is a bevel gear wheel J, workinginto a similar wheel, also marked J, which latter is placed on the endof the shaft which carries the eccentric for giving the deliveryfollower P, motion in unison with the pressure followers (beforedescribed), for forcing the pressed bricks or clay out of the one set ofmolds, while the pressure followers are pressing another set, in theneXt succeeding .series in the mold wheel. Each set of molds contain siXcases, and consequently the followers should be made with siXcorresponding divisions-one for each case. In this machine I haverepresented six cases in each set of molds, but I do not confine orlimit myself to this number, but intend to vary the construction in anymanner I deem essential,

so long as I retain the principle of the inright of substituting suchmolds, as the shape of the bricks to be made may require, whether plainor ornamental, hollow or solid. j

The shaft Gr', carries a bevel pinion wheel I', which works into anotherlarger bevel wheel J on a shaft provided with arms (as seen in reddotted lines in Fig. 1,) in the clay hopper L', for working the clayinto proper consistency for molding, and forcing it down through thechute N', into the molds in the mold wheel, which has an intermittentrotary motion underneath said chute, stopping just long enough at eachone third of a revolution to charge the molds with clay.

Y, is a stationary table immediately under the mold wheel V-the moldwheel turning just far enough above it, to run easily, and prevent theunpressed clay in said molds from falling out. After the clay is pressedin the mold, it will sustain itself therein (the table, Y, ext-ending nofarther than where the pressing` followers catch and press the clay),thus giving free motion to the upper and under pressure followers intothe molds. Vhen the mold wheel V, cornes around to the deliveryfollowers, it stops momentarily until the three operations areperformed, viz: lling one set of molds with clay,-pressing the set offilled moldsand the delivery of the set just previously pressed, andthese operations are continuous and uniform so long as the driving poweris applied to the machine. On the extreme end of the shaft which carriesthe delivery follower, is a chain spur wheel J", around which, andaround a similar wheel J passes a chain O', the links of said chaincatching over the teeth in said wheels and communicating motion the oneto the other. The chain wheel J', is arranged on a shaft I', on whichsaid shaft is also arranged two other similar spur wheels K", K", overand around which pass the carrying chains 13'- these chains also passover another set of chain wheels L", L", on the opposite end of themachine, the links in said chains catching over the teeth in said chainwheels, and by which means they receive a continuous, horizontal motionfor carrying off the pressed bricks.

S", is a friction roller, under which the chains P', pass, so as to keepthem up to such a degree of tension, as to catch and carry out from theunder side or bottom of the box Q', the boards or platforms R', (onwhich the pressed bricks are received and carried out of the machine)and convey them immediately under the delivery follower, at the propertime to receive the bricks when the follower comes down. The box Q', ismade to contain any suitable number of platforms or boards on which thebricks are received and carried away. These boards are laid into saidbox one on top of the other, and as the carrying chains P', pass alongclose underneath said box, small projections (2) on said chains catchagainst the lowermost of the pile of platforms, moving it out fromunderneath the others, and carries it immediately under the deliveryfollower, where it receives the pressed bricks, and passes them forwardout of the machine. The boards or platforms when any number of themaccumulates, are carried back and again piled up in the box Q', so as tokeep a full supply for the machine while operating.

I have stated that, the mold wheel has an intermittent rotary motion,this it receives as follows: A prolongation of the lower shaft I, (asseen at D', Fig. 2), carries a cam C, which operates a lever B. To thetop of this lever B', is fastened aV chain A', which passes around in agroove in the edge of the mold wheel, thence over a friction pulley, andterminates in a weight E a side view of which arrangement may be seen inFig. 4. On this chain A', is a catch piece a, which drops into aninclined gain in the groove or edge of the mold wheel as seen in dottedlines in Fig. 8, and by which the saidmold wheel, is drawn around onethird of a revolution, by each throw of the lever B', and when the levercomes back, by the operation of the cam, the weight E', slips or drawsback the chain (the catch piece slipping out of the inclined gain)without turning back the mold wheel, its motion being in one directionby intermittent movements as heretofore described. A trigger Z, is soarranged and operated by a cam 2 on the lower shaft I, as to lock themold wheel when it performs its one third of a revolution, a pin on saidtrigger dropping into a catch in the underside of the mold wheel; and tounlock it when it is about to make the' next portion of a revolution.This arrangement of cam and lever motion may be seen on a reduced scalein Fig. 5, where I, represents the shaft and 2, the cam on it, whichfo-rces down the lever 3, and by means of the rod 4L, pulls down out ofconnection the trigger Z, from the mold wheel V. After the cam haspassed over the lever, the weight 5, on the end of the trigger throwsthe catch pin again into action to lock the mold wheel at the propertime, and by altering the throw of the cam or the length of the leverthis may be done with the greatest precision.

The frame of the machine may be constructed in any well knownsubstantial manner, and as it may be varied to suit the peculiarcircumstances of the case need not be fully described, one method ofconstructing it being clearly shown in the drawings.

Having thus fully described the nature of my invention, what I claimtherein as new and desire to secure by Letters Patent, is,

The box or reservoir of platforms with the carrying chains or theirequivalents provided with suitable projections for catch ing, drawingforward, and carrying irnlnediately underneath the delivery follower theboards or platforms for receiving the pressed brick, and by which theyare con- 10 veyed out of the machine, substantially as described.
